FILM-PACK.

Specification of Letters Patent.

Patented Dec. is, 19.13.

Application filed October 22, 1912. Serial No. 727.165.

To all whom it may concern:

Be it known that I, J AMES EDWIN Perri- BONE, a citizen of the United States, and a resident of St. Louis and State of Missouri, have invented certain new and useful Improvements in Film-Packs, of which the following is a specification.

My invent-ion is an improvement in film packs, and has for its object the provision of a pack of the character specified of greatsimplicity convenient of manipulation, wherein the films are attached to a continuous strip so arranged that at no time during the manipulation of the films is there more than a single tab exposed, wherein the mov-' ing of each film from exposed position uncovers the succeeding film, the strip to which the films are attached being so folded that each fold when pulled straight, will move the film attached from the front to the rear.

A further object of the invention is to arrange the strip, so that each fold of the paper when drawn away, may be torn off, leaving a tab to move the next film from the front to the rear.

' In the drawings :-Figure 1 is a perspec-' tive view of the pack before use, Fig. 2 is a similar view of a art of the pack with the safety cover withd i'awn, Fig. 3 is a perspective View of the metal support, Fig. 4 1s a perspective View of the supporting frame for the opening of the pack, Figs. 5 and 6 are sections on the lines 5-5 and 6 6 respectively of Fig. 3, Fig. 7 is a central vertical section through. the pack, Fig. 8 is a horizontal section, Figs. 9 and 10 are on larged vertical longitudinal sections showing different ositions of the parts during the manipulation of the pack, and Fig. 11 is a perspective view of a portion of the supporting strip showing the method in which thefilms are attached.

The present embodiment of the invention comprises a case formed from a single piece of suitable material, as for instance, light card-board, having its side edges and ends flanged laterally and then doubled upon itself transversely to form the case 1, the side flanges lappin upon each other and being secured toget er as are also the end flanges. The end that connects the front and the back of the case is provided with I a slot 2, through which the tabs for moving the film extend, and the front of the case is cut awayto form an opening 3 for exposing the films.

'1 The metal support consists of a sheet 4 of Qsuitable material, having its side edges flanged as shown at 5, and the ends of the strip are cut away from the side flanges 5, so that the said flan es extend at both ends beyond the body 0 the support, as indicated at 6 and 7 in Fig. 3. One of the ends is headed as shown at 8, and at each end of the bead a tongue 9 is separated and extends inwardly alongside the adjacent side flange 5, the said tongue being curved upwardly away from the body of the support and At the opposite end of the body, a portion 11 of the material of the bod is separated fromthe remainder, and is 0 set upwardly from the plane of the body, the said por tion 11 being connected to the body by means of tongues or strips 12, cut from the mate- 11, a clip 13 is provided, the said clip overlying the upper face of the portion 11.

The frame of the opening through which the pulling tabs extend is shown in Fig. 4, the said frame being formed from a strip of heavy paper or light card-board, having a longitudinal slot 14 at approximately its center and the stri is doubled upon itself longitudinally at t e slot. The side edges of the strip are then bent backwardly upon the body to form flanges 15 and 16, and one of the said flanges 16 in the present instance, is seated upon the upper face of the port-ion 11, the edges of the said flange 16 engaging the clips 13, and the free edge of the flange 15 fits against the inner face of the back of the case 1. The flange 15 as shown in Figs. 7 9 and 10 is of greater width than the flange 16.

The films 17 are connected with a strip 18 of tough paper of lesser width than the film, and each film is secured upon one face of a sheet 19 of black paper. Each of the sheets 19 is provided with a reduced portion 20, Whose free edge is pasted or otherwise secured to the strip 18, and one end of the film is secured to the sheet 19 at its junction with the portion 20.

A plurality of tongues 21 are cut from the sheets 19, five being used in the present instance, and eachof the said tongues 21 is pasted or otherwise secured to the one face of the film. Each of the reduced portions 20 is provided with an indicating mark ,22, at one side of the end connected with the strip 18, and an arrow 23 is printed on the thence downwardly as shown at 10 in Fig. 3;

rial of the body. At each end of the portion said portion adjacent to the indication. Along the said end are printed directions for tearing off the strip. The said directions 24 read Grasp tab here and tear off It will be understood that as a rule twelve films are provided in each pack but for the sake of convenience in illustration, only six are shown in the present instance; The mounting however, is alike, and it is not thought necessary to show more.

The portions 20 are connected to the strip 18 in spaced relation and the portions 20 of the sheets 19 are of the same length. The pack is placed in the case after being folded, and to fold the pack the sheets 19 and the films are arranged in superposed relation with the films on the under side and with the portions 20 of the sheets extending outwardly. The strip 18 is then folded between each of the adjacent films as shown at in F igs. 8, 9 and 10. The films and the sheets 19 are placed on one side of the-support 4 while the folds 25 of the strip 18 are placed on the opposite side. The films are placed on the opposite side of the support 4 from the tongues 9 and 12, and the connection that is, the portions 20 of the sheets 19 pass around the bead 8, the said bead acting as a roller for reducing friction when the pack is manipulated.

A safety cover 26 of black paper corresponding in all respects to the sheets19 of the films is placed in front of the uppermost film between the said film and the opening 3 of the case. The safety cover .is secured to the strip 18 in precisely the same manner as are the sheets 19, the said safety cover 26 having a reduced portion 27 corresponding to the reduced portions 20 of the sheets 19. The free end of the strip 18 is passed through the slot 141 of the frame for the opening 2, and the free end thereof is cut in triangular form as shown at 28 in Figs. 1 and 2, and the words Safety cover are printed on the exposed tab.

The strip 18 is provided with two cuts 29 and 29 at each fold, the said cut-s converging toward their outer ends. The inner end of each cut is spaced apart from the side edge of the strip 18 and their outer ends are spaced apart slightly from each other as shown in Fig. 2. The arrangement is such that by grasping the paper at the point indicated by the inscription 24 and tearing off the projected portion of the strip 18, a tab 30 will be leftby means of which the succeeding fold of the strip 18 may be withdrawn to move the exposed filmfrom the front to the rear of the case.

In operation, the pack may be sealed in the usual manner by a seal connecting the edge of the opening 3 with the safety cover. If so sealed, the seal must be broken before the'pack is placed in the camera. After the pack has been placed in the camera with the seal broken, the tab 28 is grasped and pulled outward until the indication 22 appears. The first film is now exposed and after the said film has been exposed to light by snapping the camera, the succeeding tab formed by tearing off the projecting portion of the strip 18 may be grasped to move the exposed film to the rear of the case.

It will be understood that as each film is uncovered, the folded portion of the strip 18 is torn away.

It will be evident that however many films are used, there will be but one tab exposed at any one time, so that there can be no danger of moving a film before it has been exposed. The case formed from a single sheet of material as specified having side and end flanges, is exceedingly strong, since the side walls and one end wall are doubled.

The tongues 910 and the strip 11 of the support hold the films and the backing sheets at the front of the case and the flanges 5 guide the strip in its movement. It will be noted from an inspection of Fig. 8 that the said strip is inside the tongues 910 and 12.

It will be noted that three of the tongues 21 are secured to the face of the film intermediate the side edges thereof, while the other two, that is, the outermost ones are secured to the corners of the film. The out- ,ermost tongues hold the films at the corners, and prevent the film catching as it is moved in the pack.

It will be noted also that a strip 31 of plush is secured to the bottom of the case and a similar strip 32 is secured to the frame at the opening 14:. The said strips 31 and 32 are for the purpose of shutting out light and reducing friction. The black backing sheets are glossy on their rear face 105 to reduce friction and in the present instance the gloss is produced by a gum solution, which may be used to cement the tongues to the film and to cement the extension to the strips 18.

Instead of using a seal to seal the pack, the tab 28 shown in Fig. 1 may be sealed to the safety cover as shown in the said figure. When so arranged a separate seal is unnecessary and there is no possibility of loading 115 the camera with a sealed pack.

The particular arrangement of the tongues 21 prevents any catching of the end v of the film as it is drawn to the rear of the case. The utilization of the first tab for a 120 seal absolutely prevents the failure to break the seal, since the safety cover cannot be withdrawn until the tab is released.

The employment of a single piece of card board or'paper inthe formation of the case 125 provides a double thickness of material at each edge and at one end, thus making a very strong and rigid construction with a minimum. of paper or card board.

It will be noticed that the spur or lug 33 130 is struck up from the metal support at the end adjacent to theportion 11 of the said support and at the center of the said end of the support, the said spur extending in the opposite direction to the said portion. The spur or lug is pointed and passes through the ends of the backing sheets as shown in Fig. 9. hen the folded strip with the films is placed on the support, the free ends of the backing sheets are pressed-toward the support in such manner that the spur passes through the said free ends. The spur holds the loose ends of the backing sheets in place and prevents any possibility of moving more than one film at a time. The sheets are easily removed singly however, the spur tearing out as the films are Withdrawn.

In folding the paper or card board forming the case, the inside end flange 34: is provided with three or more spots of adhesive and that portion of the strip forming the top of the case is creased transversely at approximately the center of the case as shown at 35 and the side flanges are clipped transversely at the crease. When now it is desired to open the case, the flange 34: is separated from the outer flange 36 and that portionof the top of the case between the line 35 and the flap 34. may be turned up as shown in Fig. 7 in the shape of a cover, to permit the removal of a portion or all of the contents of the case.
